SPECIFICATION forming part of Letters Patent No. 395,606, dated January1, 1889. Application filed December 14, 1887. Serial No. 257,886. (Nomodel.)

.To all whom zt may concern.

Be it known that I, LEWIS P. VOODS, a citizen of the United States, anda resident of Blairsville, in the county of Indiana and State ofPennsylvania, have invented certain new and useful Improvements inGrates; and I do hereby declare that the following .is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the saine, referencebeing had to the accompanying drawings, which form a part of thisspecificae tion, and in which- Figure l is a front perspective view ofmy improved nre-grate. Fig. 2 is a rear perspective vi ew of the same,showin g a portion broken away. Fig. 3 is a horizontal sectional view.Fig. 4 is a transverse section on the line Fig. 3; and Figs. 5 and G aredetail views, in perspective, of the rear and side fire-plates.

Like letters of reference indicate corresponding parts throughout theseveral figures.

My invention has relation to improvements in portable grates forlire-places and it has for its object to provide a grate which may beadapted to be inserted into any ordinaryiireplace; and it consists ofthe peculiar arrangement and combinations of parts of the same, ashereinafter more fully set forth.

Referring to the accompanying drawings, the letter A represents the rearpiece of the frame of the grate provided with vertical strips B, andalso having suitable draft-open ings, C, in its lower end.

The side pieces of the frame are indicated bythe letters D D, and areeach provided with edge strips, E, and also have suitabledraft-openings, F, at their lower ends.` The upper parts of these sidepieces are inclined or slant-ing at G, while the eXtreme upper pointsare squared off and form a horizontal surface. To this upper horizontalsurface a top piece, I-I, is secured, the ends of the said top piecesprotruding beyond the side pieces.

'An inclined top piece, I, is secured to the inclined upper portion ofthe side pieces, of a width narrower than the width of the incline ofthe side pieces and provided with ribs or strips J. The ends of the toppiece, I, are extended out beyond the side pieces, and are formed orprovided with downward flanges I', said flanges fitting closely againstthe side pieces of the frame, whereby thc pieces are kept in properposition.

Inasniuch as the top piece, I, is of a width less than the width of theinclined portion of the sides, a space is left between the said piece Iand the horizontal top piece, H, forming the flue opening or passage Kof the grate.

Iithin the frame is the ordinary grate, (indicated by the letter L,)having its rear transverse bar, M, resting upon lugs N N, secured to theside pieces of the frame.

Vertical stripsv O O are arranged in the corners of the frame, extendingfrom the bottom thereof to the top, and upon which rests a cross-piece,P.

The letter Q indicates the rear tire-plate, the upper edge of which iscurved and bears against the crosspiece P. The rea-r surface of thisplate is provided with ribs or strips R, preferably triangular incross-section, and having their rear edges even with the rear edge ofthe upper curved portion of the plate and bears against the rear pieceof the frame, whereby an even bearing-surface is provided over theentire plate and warping is prevented. By the arrangement of the ribs,as well as the curved upper portion of the plate, dead-air spaces arealso formed between the rear fireplate and the rear piece of the frame.

The side fire-plates are indicated by the letters S S, the upper partsof the rear edges thereof being curved so as to provide a close iitagainst the rear lire-plate, while their outer or front edges areprovided with steps or shoulders T T, adapted to iit over the uppercross-bar of the grate. The upper edges of these plates are curvedoutward and bear against the side pieces of the frame in like manner asthe rear fire-plate, while the rear surfaces of these side fire-platesare provided. with a series of vertical strips or ribs, U, preferablytriangular in cross-section, said strips having their rear edges evenwith the rear edge of the upper curved portion of the plate to form aneven bearing-surface. A space is thus formed between the rear iire-plateand the rear piece of the frame, as well as between the side nre-platesand the side pieces of the frame, so as to permit the ready access ofthe air through the Hue-openings, thereby to a IOO great extentcounteracting injury and damage likely to arise from the extreme heatoccasioned by the iire, and preserving the frame from these injuriousconsequences. This construction also prevents the radiation and loss ofheat through the surrounding wall or setting of the grate.

Having thus described my invention, l claim and desire to secure byLetters Patent of the United Statesl. The combination of the rear piecehav ing vertical ribs or projections, the side pieces each provided withan inclined upper portion terminating in a squared-off or horizontalsurface and having edge ribs or strips, the horizontal top piece securedto the squared-oit portions of the side pieces and having extendingends, and the inclined top piece provided with strips, thel ends of saidinclined piece extending beyond the side pieces and formed or providedwith downward flanges engaging therewith, said inclined top piece beingalso of a width less than the width ot' the inclined portions of saidside pieces, whereby a space or smoke-outlet is formed between the upperedge of said inclined piece and the rear edge of the horizontal toppiece.

The combination of the iframe having the vertical outer strips or ribs,the rear iire-plate having a curved upper edge and provided withvertical ribs or strips upon its rear surface, the side nre-plateshaving the upper part-s of their rear edges curved, their outer or frontedges provided with steps or shoulders, their upper edges curved outwardand their rear surfaces provided with vertical strips or ribs, thecorner-strips, and the crossstrip having the ends thereof resting uponthe tops of said eorner-strips- In testimony that I claim the foregoingas my own l have hereunto affixed my signature in presence of twowitnesses.
